Oh, I know that feeling. Airports seem to be designed to be as uncomfortable as possible, to make human beings want to leave. Which is fine if nothing is delayed, and planes take off between say 11.00am and 3.00pm, not at Stupid O'Clock.

It can hardly be a coincidence that no language on Earth has ever produced the phrase, ‘as pretty as an airport.’ Airports are ugly. Some are very ugly. Some attain a degree of ugliness that can only be the result of a special effort.
-Douglas Adams
